基于自然通风建筑的热舒适模型研究

         

摘要

Aiming at the insufficiency in thermal comfort standards for naturally-ventilated buildings based on population,area and climate characteristics,the domestic existing thermal comfort evaluation models of naturallyventilated buildings are introduced,including modified PMV models,climate adaptive models and their modified models,with a view to provide a reference for future study.The results show that building energy saving potential can be exerted well by the use of thermal comfort evaluation models for naturally-ventilated buildings to guide the architectural design,air conditioning and heating equipment operation.Domestic thermal comfort study samples are abundant,but have not yet established shareable complete human thermal comfort research database.So it is difficult to form a standardized thermal comfort evaluation system.Various models have advantages and disadvantages when they used to evaluate indoor thermal comfort of naturally-ventilated buildings.The follow-up study should consider the error correction and focus on the combination of PMV model and adaptive model,and finally form a more comprehensive lumped parameter evaluation model which can combine theory of human body heat balance with human body adaptability.%针对目前基于各地区人口、地域、气候特点的自然通风建筑热舒适标准不够完善的问题,系统介绍了国内现有的自然通风建筑热舒适评价模型,包括修正PMV模型、气候适应性模型及其修正模型,以期为今后的进一步研究提供参考.归纳的结果表明,利用自然通风建筑热舒适评价模型指导建筑设计以及空调、供暖设备运行,可以很好地发挥建筑节能潜力.国内热舒适研究样本充裕,但尚未建立可共享的完整的人体热舒适研究数据库,难以形成规范的热舒适评价体系.各类模型在用于评价自然通风建筑室内热舒适性时各有优缺点.后续研究应考虑误差修正,并注重PMV模型和适应性模型结合作用机理的探讨,最终形成能够综合展现人体热平衡理论和人体适应性理论相结合的更为全面的集总参数评价模型.
